Curiously, after restarting again because I had to kill Eclipse because it seemed to be hung for several minutes after I removed a project from my Tomcat server, the 4 errors in the pom.xml appeared again before it finished all the startup tasks, but once it finished thrashing (validating, compiling, caching, et cetera), the errors in the pom went away.
